I guess it's generic vegetable oil as opposed to Canola oil or Peanut oil? I'd actually suspect that a mindset of buy whatever oil is cheapest from Sysco would pursue cheapness in other areas as well including kitchen supervision/skills.

I wouldn’t suspect that at all—some recipes (like certain kinds of “street food” from different countries actually call for the use of cheaper oils :)

I doubt it makes any appreciable difference anyway most of the time although Canola oil and Peanut oil do have a slightly higher smoke point than vegetable oil.
